I am primarily referring to the signal level. The first call returns a
plausible value e.g. -78dB. All subsequent calls return the same value,
regardless of receiver position (moving the laptop).

It almost looks like a static value that gets initialized and then 
does not change.

There is a similar behaviour for scan results: the signal levels reported
for stations remain the same for all subsequent calls. Previously these
also changed with time and position of receiver.

Sorry forgot to mention: application and operating system both 64 bit,
the bug submitted to wavemon also mentioned 64 bit.

Thank you for the reply -- maybe this means that the root cause is in a
different part; I would not know which at the moment.
